The Fastest Available U.3 PCIe 4.0 NVMe SSDs Are Now Shipping

The Fastest NVMe U.3 SSDs

An evolution in storage technology is on the horizon, and KIOXIA is proud to lead the way. In fact, we were the first company to publicly demonstrate PCIe® 4.0 SSDs at Flash Memory Summit 2019. Now, we’re delivering these next-generation drives that will steer the performance of enterprise and hyperscale data centers to the next level. Our PCIe 4.0 SSDs also support the SFF-TA-1001 specification (also known as U.3), allowing them to plug into universal backplanes (SFF-TA-1005 compliant), which support SAS, SATA and NVMe™ SSDs. This allows OEMs and customers to buy one type of server and plug in any combination of drive interfaces into any drive slot.

But, don’t just take my word for it.

IDC Research VP Jeff Janukowicz said, “SSDs, such as KIOXIA’s CM6 and CD6 Series, will help enable customers’ transitions to PCIe 4.0 and grow PCIe SSD unit shipments to over 50% of the enterprise market.” KIOXIA is honoring our commitment to customers to lead in the NVMe space by delivering some of the fastest available 2.5-inch1 PCIe 4.0 SSD solutions.

Our new CM6 Series Enterprise NVMe SSDs are ideal for high-performance computing, artificial intelligence, caching layer, financial trading, data analytics, and more. They’re available in capacities from 800 gigabytes (GB)2 to 30.72 terabytes (TB) - with 50% more capacity and 23x the throughput – in only 27% of the space of the highest capacity hard disk drive.

The new KIOXIA CD6 Series Data Center NVMe SSDs are perfect for large-scale data center deployments and general-purpose applications, such as database, cloud computing, virtualized and containerized environments, web servers, and media streaming. You can count on capacities from 960GB to 15.36TB, with 1.0M IOPS and 6.2 gigabytes per second throughput.

Both series include a broad range of security and encryption options and are on the UNH-IOL Integrator’s list for NVMe 1.4 device compatibility. The CM6 has successfully passed PCI-SIG Workshop compliance.

Fastest available claim based on Industry leading 50GB/s performance demonstrated at MS Ignite, November 2019. Configuration tested with AMD-based server from QCT, Tri-mode HBA from Broadcom and eight KIOXIA CM6 Series NVMe/PCIe SSDs, running a performance benchmarks in a Microsoft Azure environment.

"2.5-inch" indicates the form factor of the SSD. It does not indicate drive's physical size.
Read and write speed may vary depending on the host device, read and write conditions, and file size.

Definition of capacity: KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1Gb = 2^30 bits = 1,073,741,824 bits, 1GB = 2^30 bytes = 1,073,741,824 bytes and 1TB = 2^40 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
